Description

The KLA-Tencor Confocal Review Station (CRS) is an automated laser/white light microscope system used for classification of defects on both bare and patterned wafers, using defect maps generated by a variety of instruments. The CRS combines a brightfield/darkfield white-light microscope with a laser confocal microscope, automated wafer handling, and controlling software.

The CRS can display any combination of a 2D focal plane image, a 3D surface image rotated to any orientation, any horizontal slice of a volume image, and vertical 2D cuts through any of the 3D images in XZ or YZ planes. The laser scan amplitude can vary for 1x, 2x, 4x, or 8x zoom within the same magnification of the microscope, providing on-screen magnification up to 20,000x with a 100x objective at Zoom level 8.

An important feature of the confocal microscope is its extremely narrow depth of focus in laser light, which makes it possible to view images of individual layers in semiconductor structures, and to resolve structural and defect features as small as 0.15 µm.

The CRS can be configured from fully manual operation to fully automated operation. There are manual and automatic options for cassette loading, wafer loading, deskew, defect inspection and analysis, image capture, data storage, and communication. The CRS can run automatically using locally stored recipes, or can receive commands and respond to them over a network.

InstraView Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive. With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
